A Simulation Method for LIDAR of Autonomous Cars

[摘要] Vehicle-mounted LIDAR simulation module is an important part of autonomous car simulation test platform. According to the working principle of LIDAR, its working process and interface can be simulated in the digital simulation environment. The environment includes LIDAR emulation module, high precision 3D scene model and data interface module. The LIDAR simulation module uses GPU(Graphic Processing Unit)to calculate the depth of high-precision 3D scene and output the results through data interface. On the PC workstation, 64 lines vehicle-mounted LIDAR can be implemented for real-time simulation of large-scale road scene.
